Validate a JSON Payload

Learning goals​

Build and inspect a typed validation contract.

Quick reference: Level 2; starter; output type validation_summary; estimated cost: none.

Architecture​

Text alternative: The graph contains FlowBeads/input, JSON/JSON Parse, ComponentBeads/const Object, Test/JSONSchemaValidator, DataBeads/template, FlowBeads/output. It accepts public input and returns a public result.

Prerequisites​

None.

Connections​

None.

Secrets​

No paid secret is required.

Build and run​

  1. Review the schema constant.
  2. Run valid and invalid payloads.
  3. Inspect the validation summary.

Use this fixture in the Test panel:

Valid customer
{"name":"Ada","email":"ada@example.com"}

Expected result​

  • isValid is true
  • errors is empty
  • summary is returned

Open the persisted run and verify the node timeline. Browser sinks appear in the Inspector; public output appears in the run result when enabled.

Side effects and cost​

This Braid has no external side effect.

Cost: none. DataBraid stores summaries and structured errors, not secret values.

Extensions​

  • Change the fixture and compare the node-level timeline.
  • Add a Data Probe before the final output.
  • Save a known-good fixture for regression testing.
